POLY PROPYLENE (PP)
GENERAL INFORMATIONPolypropylene copolymers have outstanding chemical resistance and show the highest resistance of all thermoplastics to organic chemicals. High density polypropylene has some similarity with Polypropylene copolymers in respect of chemical resistance, although here again Polypropylene copolymers possesses the additional advantages of being usable at higher operating temperatures. Both the polymers have similar solubility parameters and tend to swell by the same solvent. In both the cases the absence of any possible interaction between the crystalline polymer and the liquid prevents solution of the polymers in any liquid at room temperature. Polypropylene copolymer also possess an extremely high resistance to inorganic environments. It is not attacked by aqueous solution of inorganic salts not by most mineral acids and bases, even when in concentrated form, though it is liable to be attacked by oxidising agents e.g. 100% fuming Nitric acid and Sulphuric acid or the halogens.
